This study aims to analyze actual conditions of the present national defense information network operation, the structure and management of the system, communication lines, security equipments for the lines, the management of network and software, stored data and transferred data and even general vulnerable factors of our army tactical C4I system. Out of them, by carrying out an extensive analysis of the army tactical C4I system, likely to be the core of future information warfare, this study suggested plans adaptive to better information security, based on the vulnerable factors provided. Firstly, by suggesting various information security factor technologies, such as VPN (virtual private network), IPDS (intrusion prevention & detection system) and firewall system against virus and malicious software as well as security operation systems and validation programs, this study provided plans to improve the network, hardware (computer security), communication lines (communication security). Secondly, to prepare against hacking warfare which has been a social issue recently, this study suggested plans to establish countermeasures to increase the efficiency of the army tactical C4I system by investigating possible threats through an analysis of hacking techniques. Thirdly, to establish a more rational and efficient national defense information security system, this study provided a foundation by suggesting several priority factors, such as information security-related institutions and regulations and organization alignment and supplementation. On the basis of the results above, this study came to the following conclusion. To establish a successful information security system, it is essential to compose and operate an efficient 'Integrated Security System' that can detect and promptly cope with intrusion behaviors in real time through various different-type security systems and sustain the component information properly by analyzing intrusion-related information.

Information types and display methods according to the relation between frequency of exposure and degree of cognition was suggested by this study as a way to enhance effective communication by information in aspect of user cognition. First of all, we ascertained the relation between frequency of exposure and degree of cognition by literature research for cognitive psychology and cognitive engineering psychology, results are as follows based in it. First, we suggested information types and attributes for visualization as 'Framework' which helps designers understand cognitive demands of users. Specifically, there are 4 types(STM, STA, LTM, LTA) of information according to the relation between frequency of exposure and degree of cognition, cognitive characteristics for each types and 'attributes matrix for visualization' which is consisted of 14 attributes of high -quality information and resorted by the types. Second, we suggested a guideline for display methods according to depth of information in the design process of information contents. For display methods of STM, STA information as primary information, we suggested "Attribution theory of Distinctiveness", "Advance Organizer", "Progress Closure", "Affordance", for display methods of LTM information as multidimensional information, we suggested "Modularity", "Consistency", "Mimicry", "Mnemonic Device". We had found from this study that there are distinction of status for attributes of information visualization according to information types or depth, and various display methods by them.

Urban design claiming the notion of 'Sustainability', which inevitably includes ecological complexity, is normally geared towards the reflection of environmentally-friendly technical guidelines in the existing planning process. Although physical planning should be combined with economic, social, cultural, environmental issues, and policies, it is conducted conventionally as the sum of the closed sectoral approaches of planning. To overcome this limit, Design Charrette was invented for sustainable urban design or community design, which should consider the complexity of diverse issues. This design process unveils complicated and divergent problems and a variety of stakeholders participate in the integrated design simultaneously and cooperatively. Because Design Charrette must also be a process of agreement, it is used for sustainable community design. The aim of this study was to introduce Design Charrette as an alternative of Korean sustainable urban design, which is regarded as 'making guidelines related to green principles'. For such a purposes, the definition and differentiation of Design Charrette will be explained with an analysis of the introduction background, benefit and procedure. The contents, system and process of Design Charrette will be analyzed through case studies in Canada, where this method of design is widespread. In the last part, the implementation system (the comprehensive system of organization / content and direction of planning / process and output) will be deduced after concentrated analysis of one respected case, 'Sensitive Urban Infill Charrette' of the City of Surrey. This implementation system will be a crucial reference to develop Korean Design Charrette.

This study examines the status of major corruption in the public and private sectors in Korea. This study adopts the secondary data analysis method, and uses 'The Status of Corruption in Korean Society' released by Ipsos in March 2019. The annual difference analysis is conducted to examine the trend of major corruption, and the results are as follows. First, in the public sector, the number of conspicuous crimes, such as bribery, has decreased, but intelligent crimes that are not easily detected, such as abuse of authority, are increasing. In the private sector, embezzlement was on the decline, but breach of trust remained at a certain level. Second, from 2003 to 2017, the average annual change rate of major corruption in the public sector was 8.0%, while the private sector was 1.8%. Third, the public sector has seen a slight increase in corruption except in 2015, but the private sector has been declining since 2014. This study is different as it makes academic contributions by offering three anti-corruption measures; changing the culture of high power distance, changing the culture of low corruption perception, and abolishing the culture of impunity. Empirical studies using primary data that separate the two groups are required.

Corporations operate within long term strategy. The Chief Executive Officer (CEO) makes decisions and has responsibility for all executive activities which affects the corporate performance. If the CEO makes strategic choices through reasonable decision making, it could affect corporate performance and corporate's rise and fall. So the CEO's decision making is very important. As rapid change in the digital technology environment happened, through digital transition, corporations have been working on increasing corporate performance by practical and academic methods. However prior research was restricted to CEO's affect on organization, innovation or innovative activities and there is a lack of research linking CEO's characteristics to digital transition and corporate performance. As the digital age is coming, research on how CEO's characteristics affect digital transition and corporate performance is direly needed. From the case of domestic Big Data corporation RSN Co. ltd's digital transition success, understanding characteristics of CEO, digital transition and corporate performance through prior researches, and developing research model and research proposition was set. Research was performed on RSN co. ltd's case analysis, and how characteristics of CEO's matter on digital transformation and corporate performance. As a result of the proposition, when the CEO conjugates digital technology, the corporation was able to successfully complete digital transition and it also affects corporate performance. Also, this research's other point is that CEO's may have limits on thoughtful decision making. It is judged that it is necessary to try an empirical study in the future.

The purpose of this research is to create a preferable corporate culture under the SmartWork environment. There is growing interests in SmartWork, which can satisfy the compatible conditions of government's carbon emission restriction policy, corporate efficient expense reduction, productivity maximization, and each individual's work and a family. Due to the interests and the rapid development of IT technology, a realistic condition for SmartWork is established but the promotion without a sufficient preparation, such as legal examination and relevant systems, created much confusion and very few companies are introducing it. This paper discusses that a social agreement should be reached through adjustments among parties interested, such as government, companies, and employees, studies the WIN-WIN plan that individuals and organization can grow together, and proposes a new corporate culture under the SmartWork environment. SmartWork has more than the simple meaning of 'remote working'. SmartWork, a method of smart working, means a transition to a new paradigm that minimizes moving for work and work & human move together, and a change from a work-oriented culture to a human-oriented culture. This paper summarized the role of government and companies for the successful introduction of SmartWork, and proposed that a government level 'SmartWork Activation Executive Committee (tentative name)' with a strong promotional power would create a new culture of SmartWork and form a civilian consultative body to support SmartWork corporate culture creation & expansion in the private corporate area, in a tuning with Ministry of Public Administration & Security, Ministry of Labor, Ministry of Gender, and Communications Commission.

The purpose of this study is to examine the effects of work-family conflict factors on depression in Korean married women. For the analysis of the research, we were used in the 5th year data of Korean Longitudinal Survey of Women and Families. The subjects of this study were married women who were living with their husbands and wage workers, and the final analysis was 1,299. As a hierarchical regression analysis result, the work-family conflict of the working married women had a significant effect on depression. Especially, conflict from family to work has the highest effect on depression(${\beta}=.150$, p<0.01). This study suggests that traditional gender role pressures can have a negative impact on the mental health of working women. Therefore, it is necessary to take appropriate social policy measures to alleviate work-family conflicts of married working women.
